Application filed September 13, 1828, Serial No. 135,294, and inrGerma'ny September 18, 1925.

Emulsions'of liquid or solid materials diflicultly soluble or insoluble in water or not miscible therewith are usually prepared with 'the aid of soap or substances possessing simi- 6 lar properties, such as Turkey red oils, organic sulfonic acids and the like; solid materials are emulsified in the form of amelt or .of a solution in a suitable ,solvent. 'In many cases, however, a satisfactory result is not- 10 obtained by thismethod. For example it is not possible to form' a stable emulsion oi olive oil in water with the aid of soap or-sul-- fonic acids of soap-like character.

We have now found that oils, fat s, waxes hydrocarbons, alcohols, ketones,esters, and

other materials insoluble or diflicultly soluble in water or not miscible therewith, whether solid or liquid, can be converted into emulsions which are very stable even when diluted with water and in many cases even in the presence of acids by employing a sulfona tion product of an organic substan'ceposse'ssl ing' at least six carbon atoms in its molecule,

in conjunction with a protective colloid, such as lue, gelatine, casein, agar-agar, dimethylce Mesa and the like, or water-soluble gums such as gum arabic or similar materials. a

As examples of substances havingsoaplike properties applicable according to the present invention we mention Turkeyredeil, sulfitelcellulose waste liquor, aIkyIatedardL matic sulfonic acids, especially thoseofthe n ph halene series and the like.

Instead of adding the said ingredients of the two groups successively in the course of I can be advantageously employed for the preparation of mineral or artificial materials such asinorga-nic or organic pigment colors, soot, sulfur, blanc fixe and the like, in a finely subdivided state, for which purpose the said mixtures are added to the liquid in =0 which the said materials are prepared or by ;ors possess avery great coloring and coverm ower.

e following examples'will further illustrate. how our invention may be carried out in practice, but the invention is not limited to these examples. The .parts'are by weight, unless otherwise stated.- I 7 Example 1 l l ,0 parts of a per cent aste of isopropyl naphthalene sulfonic acid sodium salt are .stirred with 200 parts of'water and mixed with a warm solution of. parts of bone glue in about 180 parts of water. This mixture is capable of emulsifying about1600 parts of olive oil. It may be employed directly for making emulsions or it may be concentrated on a hot water bath while stirring or it may be evaporated to dryness in vacuo and finely powdered,

By introd'ucing,while stirring, 16 parts of olive oil into one-part-of the-powdered emulsifying agent mentioned above dissolved in 4 arts of water, a salve-like mass is obtained adder some time which by stirring with water is converted into a thin liquid of milk-like appearance.

The emulsifying agent can also be prepared by intimately mixing 95 parts of finely powdered glue with 35 parts of isopropylnaphthalene sulfonic acid sodium salt in the solid state. 1 part of this mixture dissolved in 4 parts of water is capable of emulsifying 15 or more parts of olive oil;

Example 2 10 parts of neutralized concentrated sulfite cellulose waste liquor in the form of a 20 per cent solution are stirred with about 4: parts of bone glue dissolved in about 9 parts of water. This mixture is suitable for example for emulsifying about 25 parts of olive oil.

45 parts of water. By adding 20 parts of .molten paraflin wax a white tough mass is ob- Ewample 3 10 parts of a 7 0 per cent paste of isopropylnaphthalene sulfonic acid sodium salt are stirred with 100 parts of water, and mixed with a solution of 20 parts of bone glue in tained which forms stable emulsions with water.

In the foregoing examples Turkey red 011 and salts of sulfonic acids other than isopropyl-naphthalene sulfonic acid sodium salt may be employed as substances having soaplike properties. The glue may be replaced for example by gelatine or by um arabic.

Instead of olive oil, other oi s such as castor oil; linseed oil, mineral oils, oleic acid and the like can be'emulsified.

450 parts, by volume, of'amineral oil are added to this mixture while vigorously stirring. A salve-like mass is obtained which when mixed with dyestuffs, color lakes, pigments, soot or the like'anddilutd with water to a suitable consistency, forms a non-set ng printin ink .very suitable for graphic purposes, or instance for intaglio.'

The above proportions may be varied Within wide limits; instead of mineral oil, other oils in use in graphic industries, varnishes and the like may be employed. The

1 part of this emulsifying agent dissolved in 3 parts of water ,is capable of emulsifying- 15 parts of olive oil.

Ewample 6 100 parts of the yellow pigment color obtained from diazotized 5.-nitro-4-to1uidine aceto-aceticnnilide .are intimately ground in the dr state with 15 parts of powdered glue an 3 parts of bepgyl aniline sulfo'nic 'la' cid sodium salt. The resulting coloring matter is ver 'finely divided in comparison with the inrfizal material. It forms In a similar manner, other substances forexample casein, or gum anabic may be employed instead 61 glue. The benzyl-aniline sulfonic acid sodium salt may be replaced by sulfitfi Qll1ll9$.Q...Waste liquo anap alenesu furic.a ids and the/like. The quantities of the ingredients employed meiy be varied within wide limits.v

nstead of starting from the powdery dye stuff, it is also possible to employ an aqueous paste of the coloring matters, to min saline with the dispersing agents or their solutions, whereupon the mass is dried and ground. Grinding may be dispensed with if. the drying-is eflected so as to obtain di- 300 parts, by volume, of a. 20 percent l a drXPOWdery product solution of Example '1" l5 parts of beta-naphthol are dissolved in 500 parts of water by adding 13 parts of caustic soda lye of 40- degrees Baum and 10 parts of soda ash.

H -The prdcesses described in the above examples 6 and 7 may also be carried out in the presence of substrates such as are usual in the industry of'colorlakes. I Example 8 300 parts of water are mixed with an aqueous solution of 2.5 parts of celllulose dimethyl ether and 2.5 parts of isopropylnaphthalene sulfonic ac1d sodium salt. 80 parts of olein are then caused to 'run in while continuously stirring. A homogeneous emulsion is obtained which may be employed for example for oiling wool.
